Zantac Lawsuit

Zantac Lawsuit Update: June 2024

People who developed cancer after taking Zantac (generic: ranitidine) may choose to file a Zantac lawsuit against the drug manufacturers to recover financial compensation for past, present, and future medical bills, lost wages, and other damages.

Zantac lawsuits are ongoing in California and Delaware state courts. In California, attorneys from Wisner Baum and co-counsel have secured several Zantac settlement agreements for clients who allege the heartburn drug caused their cancer. California Zantac attorneys are preparing for trial in 2024. 

In Delaware, over 72,000 lawsuits are moving forward after an order from Judge Vivian Medinilla on May 31, 2024. The order found the opinions of plaintiffs’ experts reliable and admissible, allowing them to testify at trial that Zantac causes cancer. 

Wisner Baum serves on the plaintiffs’ leadership for Zantac cancer cases filed in California State Court and Delaware State Court.

Zantac Lawsuit FAQS

  • Where are Zantac Cases Filed?

    Most Zantac lawsuit cases were initially consolidated in a federal multidistrict litigation (Zantac MDL) before U.S. District Court Judge Robin L. Rosenberg for the Southern District of Florida. However, Judge Rosenberg issued an order granting Zantac defendants’ motion for summary judgment, effectively dismissing all federal cases. Attorneys for the plaintiffs are appealing that decision, and rightfully so, but until those dismissals are resolved, the case is effectively over in the federal system.

    The Zantac lawyers at Wisner Baum didn’t have any cases filed in the MDL. Rather, we filed our cases in California and Delaware state courts—indeed, we formed consolidated proceedings in California and Delaware. Wisner Baum’s managing partner, R. Brent Wisner, serves as co-lead trial counsel in both states.

    The primary state courts with Zantac cases include:

    • California
    • Delaware Illinois
    • Illinois
  • Should I Hire a Zantac Lawyer Near Me?

    Many people have the instinct to hire a local attorney to handle their case. In a nationwide mass tort litigation like Zantac, your lawyer’s location is not as important as their experience and track record in successfully resolving cases similar to yours.

    Here’s what you should be looking for in a Zantac lawyer:

    • Proven track record in similar cases
    • Resources needed to take on major corporate defendants
    • Trial-ready litigation team that prepares cases to go before juries to maximize your compensation
    • Compassionate, friendly representation that puts your needs first
    • Availability if and when you have questions about your claim
  • What Will It Cost to Hire a Zantac Attorney?

    We provide free Zantac case reviews to anyone who fills out our contact form or calls our offices. It costs you nothing out of pocket to retain our law firm to represent you and pursue justice and compensation on your behalf. We don’t see a dime until we win your case.
  • How Much Can I Get From Zantac Lawsuit?

    Most of the people who contact our legal team want to know how much their Zantac case is worth. The truth is, we can’t give them a good answer because each case is different. What we can say is that the Zantac litigation will likely end in settlement agreements where cases are ranked using a tier system based on severity of injuries and strength of claim.
  • Who Can Join the Zantac Class Action Lawsuit?

    Anyone who purchased Zantac and can prove they did so may be eligible to participate in a Zantac class action claim. Unlike individual lawsuits against Zantac’s makers, in a class action lawsuit, plaintiffs do not have to prove that they were harmed, only that that they purchased the drug and were not warned about the Zantac cancer risk. Such plaintiffs argue that they suffered economic losses because they purchased the drug believing it was safe and would not have made that purchase had they known about the risk of life-threatening Zantac adverse effects.
  • Is My Zantac Lawsuit Part of a Class Action?

    It depends on your claims for damages. For example, if you took Zantac and were diagnosed with some form of cancer (or if a family member took Zantac and was diagnosed with cancer), you may be eligible to file a personal injury lawsuit against the manufacturers of Zantac and/or over-the-counter Zantac (OTC). An individual personal injury Zantac lawsuit allows people who developed cancer to obtain the maximum possible compensation for their injuries. Conversely, if you took Zantac and never developed cancer, you could still seek compensation by filing a class action lawsuit against the makers of prescription Zantac and/or Zantac OTC. A Zantac class action lawsuit allows consumers who purchased prescription Zantac or generic Zantac (ranitidine) to recover the money spent on purchasing the medication.
  • My Cancer is Not Listed…Do I Have a Zantac Case?

    At this time, our law firm is unable to pursue cases on behalf of individuals who do not meet the general criteria listed above. Please understand that this does not mean that you are ineligible to pursue a case or that your injuries are not substantial enough. It simply means that we do not believe that we would be able to successfully pursue a claim on your behalf.
  • How Do You Qualify for a Zantac Lawsuit?

    The general criteria listed below for Zantac lawsuit eligibility is based predominantly on court orders and prevailing scientific research. Please note that Zantac case criteria can change at any time.

What is the Current Status of the Zantac Lawsuit?

  • June 1, 2024: Delaware Zantac lawsuits are moving forward. Last Friday, Judge Medinilla issued an order that allows plaintiffs’ expert witnesses to testify at trial that Zantac (ranitidine) causes cancer. More than 72,000 claimants in Delaware Superior Court allege exposure to N-Nitrosodimethylamine (NDMA) in Zantac caused their cancer. Zantac lawsuits further allege the drugmaker defendants knew for decades that Zantac could break down into a carcinogen.   

    Wisner Baum’s managing partner, R. Brent Wisner, issued the following statement after Judge Medinilla’s order:

    “This case has always been about getting the science in front of a jury. Judge Medinilla’s thoughtful order highlights something that often gets lost in the modern world of mass torts—the central role juries must play in holding companies accountable. Now, the writing is on the wall. GSK, Boehringer Ingelheim, and Sanofi will need to answer for their forty years of misconduct, and they will be judged by the very people they lied to.”

  • May 20, 2024: Zantac lawyer R. Brent Wisner and co-counsel Jennifer A. Moore are representing Valisure in a whistleblower lawsuit alleging GlaxoSmithKline (GSK) lied to the U.S. government and the FDA about the link between Ranitidine and cancer. The lawsuit alleges that GSK concealed the link between Ranitidine and NDMA for nearly 40 years. Only after Valisure published its testing data on Ranitidine in September 2019 (after first disclosing this information to the U.S. government) did the FDA grant Valisure's citizen petition and request to remove the popular antacid. The FDA issued a market withdrawal for Zantac in 2020.  

    The lawsuit seeks damages for False Claims Act violations at the federal and state levels. Plaintiffs seek to recover treble damages, civil penalties, and other recoveries under the FCA and the State False Claims Acts.  

    “Valisure conducted the same tests that GSK did in the 1980s,” said Zantac attorney R. Brent Wisner. “The difference—instead of lying to the FDA and burying the results, Valisure turned everything over to the FDA.” 

    “GSK has a criminal history of defrauding the federal government—having been fined over $3 billion by the Department of Justice in 2012. This is worse. For forty years, GSK knowingly exposed millions of Americans to a carcinogen without their consent and bilked taxpayers along the way.” 

    You can read more about this case in our press release.  
  • March 1, 2024: As of today, there are over 72,000 Zantac cases consolidated in Delaware state court, which accounts for the majority of Zantac cancer lawsuits in the U.S. With Daubert hearings completed, we are now waiting for the Judge to decide if experts are qualified to opine on issues related to these cases, including any causal connections between Zantac (ranitidine) and the various cancers. This is a crucial test that will largely determine if the court will proceed with claims related to some or all of the various cancers.    

    In addition to the Delaware cases, there are now approximately 4,000 Zantac lawsuits consolidated in California state court. The drug maker defendants have settled several individual cases in California ahead of trial.      

    Zantac attorneys estimate that there are another 2,000 cases filed in various state courts throughout the country.       

    Our legal team is accepting Zantac cases. If you took Zantac and developed cancer, please give us a call today at 855-948-5098to see if you can join the Zantac lawsuit.  
  • January 19, 2024: A Daubert hearing in the Delaware Zantac litigation will take place on January 22 – 25 before the Hon. Judge Vivian L. Medinilla.        

    At a Daubert hearing, legal teams for the plaintiffs and the defense present their experts to educate the court on the science behind both sides of the alleged Zantac cancer connection. The plaintiffs must demonstrate that they have scientific evidence to back their claims that Zantac causes cancer. Judge Medinilla will evaluate whether the methodologies expert witnesses relied on to arrive at their conclusions are backed by sound science. If the judge determines those methodologies are valid, our expert witnesses will be allowed to testify in court and the Zantac cancer cases can proceed to trial.         

    The hearing will begin at 9:00 a.m. local time at the Leonard L. Williams Justice Center, 500 North King Street, Wilmington, Delaware, 19801.        
  • January 12, 2024: As we prepare for the first Zantac trial next month, we are in the process of finalizing the schedule(s) for the next round of bellwether trials here in California. We will have more information in the coming weeks. Our firm will also have some news on the Delaware Zantac litigation by the end of January. 
  • December 1, 2023: The first Zantac trial is tentatively scheduled to take place in February of 2024 in Alameda County, California. The case, part of the California Zantac JCCP (Ranitidine Product Cases, JCCP No. 5150), will be for a claimant who alleges Zantac caused their bladder cancer. Jennifer Moore of the Moore Law Group will co-lead the trial team with R. Brent Wisner of Wisner Baum. More details to come.

How We Can Help With Your Zantac Lawsuit

The trial-ready team of attorneys at Wisner Baum intend to hold the makers of Zantac accountable for allegedly concealing the ranitidine cancer link. With more than $4 billion in verdicts and settlements won across all practice areas, we have the experience and track record needed to secure maximum compensation for our clients.

We have filed Zantac lawsuits alleging the drug maker defendants have known for decades that the ranitidine molecule is capable of producing staggering amounts of the carcinogen NDMA when ingested as directed. Rather than warning people about the Zantac cancer risk, the drug makers willingly chose to put profit over people.

Our clients would never have purchased or used this drug had the manufacturers properly disclosed potentially fatal Zantac side effects. Outraged by the recklessness of these companies, we intend to hold them accountable for the damage they have caused.

Why Was Zantac Taken Off the Market?

Zantac (ranitidine) was taken off the market because the drug contains unacceptable levels of N-Nitrosodimethylamine (NDMA), which is a substance known to cause cancer. Testing of ranitidine drugs showed levels of NDMA above the FDA’s acceptable daily intake limit of 96 nanograms (ng) per day. For example, testing from Connecticut-based online pharmacy Valisure detected NDMA in excess of 3,000,000 ng per tablet when analyzing ranitidine products.

Valisure tests medications for consistency and quality issues. During testing, the company discovered extremely high levels of NDMA “in every lot tested, across multiple manufacturers and dosage forms of the drug ranitidine.”

Valisure’s finding was consistent with studies from Stanford University and elsewhere, which found that NDMA in Zantac was likely due to the “inherent instability” of the ranitidine molecule.

“There’s no acceptable cancer risk for a drug like this,” said David Light, CEO of Valisure.

Valisure reported its findings to the FDA in June of 2019. Three months later, the company filed a citizen’s petition urging the FDA to issue a Zantac recall and suspend all sales:

“Combined with other data from Valisure and the scientific works of Stanford University and others, the evidence presented shows this instability and the resulting NDMA occurs in the conditions representative of those in the human body and builds a compelling case for ranitidine being a likely human carcinogen.”

On Jan. 2, 2020, research laboratory Emery Pharma filed a citizen’s petition of its own noting that ranitidine is a time and temperature-sensitive pharmaceutical product that develops into NDMA when exposed to heat. In a press release, Emery Pharma noted:

“Exposure to high temperatures is a common occurrence during transportation and storage, and is of specific concern to ranitidine as there currently are no requirements for the drug to be shipped in temperature-controlled conditions and/or stored under refrigeration.”

Ranitidine is a very unstable molecule. On one side, you have the N (Nitroso). On the other side, you have the DMA (Dimethylamine). When the molecule is exposed to heat, various biological processes in the stomach, and enzymatic reactions throughout the body, it shears apart and reconstitutes as NDMA. But the formation of NDMA is not limited to the reaction in human stomach. Ranitidine can turn into NDMA in the pill bottle itself. In fact, our Zantac lawsuits allege that the drug manufacturers for decades had this problem where ranitidine turned yellow in storage. If it’s yellow, that’s NDMA. They claim they had no idea why this was the case, but our lawsuits say otherwise—they knew.” Zantac Attorney R. Brent Wisner
